Exeter

Exeter district sits on the River Exe in Devon in South West England and includes the city of Exeter and surrounding parishes. The city grew from the Roman town of Isca Dumnoniorum; fragments of the Roman walls remain alongside medieval walls and Rougemont Castle. The centre contains Exeter Cathedral, the University of Exeter campuses, the Quay and the Exeter Ship Canal, which links the city to the tidal Exe. The district functions as a local government, retail and transport hub with rail lines to London and the West Country and the M5 nearby.

Underneath narrow streets lie the city's medieval underground passages, stone-lined culverts built to house the pipes that carried spring water into town; several sections are open to guided visits and illustrate how the urban fabric was adapted to water supply needs. Local museums record Roman finds and later mercantile trade on the quay. The district combines residential suburbs, parkland and pockets of industrial estate while maintaining layers of history visible in street patterns, gates and civic buildings.
